JAMES E. WALKER, OF DETROIT, MICHIGAN, ASSIGNOR OF TWO-THIRDS TO LAFAYETTE GRIFFITH AND CHARLES F. HUNT, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 479,926, dated August 2, 1892.

Application filed March 18,1892. Serial No. 425,488. (No model.)

To all whom it may concern:

Be it known that I, JAMES E. \VALKER, a citizen of theUnited States, residing at Detroit, in the county of W'ayne and State of Michigan, have invented certain new and usefulImprovements in Oar-Couplers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in car-couplers; and the inventiou consists in the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter described.

In the drawings, Figure I is a detached per spective view of two adjoining coupler-heads. Fig. 2 is a vertical central longitudinal section of the same. Fig. 3 is a horizontal section. Fig. 4: is a detached perspective view of one of the coupling-hooks.

A is the draw-bar of the coupler, at the forward end of which is secured the draw-head B, preferably in the shape of a rectangular box secured by means of bolts 0 to the drawbar. In each draw-head is journaled in suitable bearings formed in the sides the shaft D, upon which is secured at one side of the center the coupler-hook E. This couplinghook projects forward a sufficient distance to enter an adjoining draw-head and is provided at its forward end with a hook F, which is adapted to engage over the shaft D of an adjoining coupler, as shown in Fig. 3, a portion G thereof beside the hook forming a hookbar. The shaft D is provided at one side with the lever or crank H, by means of which it may be lifted out of engagement with the hook-bar of the adjoining coupler in any suitable manner, preferably by means of the connecting-chain I and the rock-shaft J, extending to the side of the car and provided with a crank-arm K. In order to uncouple both hooks, I provide on each hook near its inner end a lateral extension L, adapted to engage beneath the adjoining hook, as plainly shown in Fig. 3, so that in disengaging either hook will be lifted simultaneously to uncouple the cars.

Pivoted in the draw-head beneath the coupling-hooks are the links M, which may be used in coupling the car provided with my hook to the ordinary link-and-pin coupler, and as in this event it would be desirable to remove the coupling-hook out of its ordinary coupling position I form the slot N in the top of the draw-head, into which the coupling-hook may be turned, as shown in dotted lines in Fig. 2, being locked in that position in any suitable manner, and to allow the link to drop down out of the way of the coupling-hook E, I form notches O in the lower face of the draw-head, so that the link may be normally longer back of the forward edge of the head, as plainly shown in Fig. 2.

My construction allows of necessary vertical movement between the adjoining ends of the cars to take up the inequalities of the track and it gives me a perfect coupling with two hooks.

hat I claim as my invention is- 1. In a car-coupler, the combination of the draw-bar, a box-shaped draw-head thereon, a transverse shaft journaled therein, a hook secured at one side of said shaft, the portion G of said shaft forming a hook-bar, and the latorally-extending lugs L, and means for disengaging said hooks, substantially as described.

2. In a car-coupler, the combination of the draw-bar, a box-shaped draw-head thereon, a transverse shaft D, journaled in the head and carrying the forwardly-extending hook, the draw-head provided with a notch N, into which the hook may be turned, and the link M, pivoted below the hook, and the notchesO in the draw-head, in which said link is adapted to engage, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES E. WALKER.
